Abstract: The present invention provides a mobile communication system based on cooperative communication that prevents performance degradation when there is a time difference between a point of time when an MCS level is measured between a relay and a terminal and a point of time when an AMC is applied based thereon. The mobile communication system based on cooperative communication according to the present invention includes a base station, a relay, and a terminal. The base station determines map information between the relay and the terminal based on channel information received from the terminal through the relay. The received channel information includes information with respect to an MCS level. The base station delivers the information with respect to the raised MCS level to the relay when a rise in the MCS level is required. In other words, the base station can control the MCS level by delivering an MCS level control signal to the relay. In order to prevent data loss that may occur when the MCS level is raised, the base station delivers the same data as the relay to the terminal during the period of time when the MCS level is changed and thus a macrodiversity gain can be obtained.

Abstract: A human body communication system for fast data transmission is provided to reduce inter-user interference by limiting a frequency band for signals, which is able to be supplied to the human body, and to increase a data rate by obtaining the maximum gain within the limited frequency band. A transmitter(10) in a human body communication system comprises a source coder(100), a CRC(Cyclic Redundancy Check) coder(101), a channel encoder(102), an interleaver(103), a mapper(104), a spreader(105), and a pulse shaper/IQ modulator(106). If the source coder(100) codes source information into digital Tx data, the CRC coder(101) inserts a CRC code in the coded Tx data. The channel encoder(102), selectively supporting a HARQ function, executes channel encoding for the output of the CRC coder(101). The interleaver(103) performs block interleaving so as to change a burst error into a random error. The mapper(104), or a constellation mapper, symbolizes the Tx data outputted from the interleaver(103). The spreader(105) executes band spreading for the symbolized Tx data using a spreading code, of which the code length is fixed according to a data rate and a limited frequency range. The pulse shaper/IQ modulator(106) creates a baseband signal, which has a limited frequency range so that the human body can maintain waveguide characteristics, for the Tx data outputted from the spreader(105) and executes digital orthogonal modulation for the created baseband signal.
